Replicator concept art available?

[M2m]

As the title suggests I am looking for some concept drawings of Star Trek (food) replicators. I couldn’t find any on the internet. So I wonder if there are some available at all..

I kind of wonder if such exists, as well. I mean, I can see how it might not, given that the concept is really "inset shelf that stuff appears on". Maybe they just turned the props or set design people completely loose on it?
